Shock-absorbing power-assisted sole

Abstract

The invention relates to a sole structure, in particular to a shock-absorbing power-assisted sole. The shock-absorbing power-assisted sole is characterized in that the sole is made of thermoplastic polyurethanes (TPU) materials; the front end of the sole is provided with a trapezoid edge (1), and the trapezoid edge (1) is a circular arc line; the heel part of the sole is provided with a vacuum air cushion (4); and the front part of the sole is provided with a short cylinder (2), and the heel part of the sole is provided with a high cylinder (3). The sole of the invention has the following characteristics: 1, the sole is provided with the vacuum air cushion, and the short cylinder and the high cylinder are arranged according to the structure of a foot, therefore, by using the pressure produced by the walking of a person, the short cylinder and the high cylinder can achieve the purpose of shock absorbing, buffering and power assistance; 2, the sole is made of MD materials and the TPU materials, therefore, the sole has better heat insulation performance so as to ensure that the temperature of the foot in the shoe is appropriate; 3, the sole can be turned 180 degrees without breaking, can effectively accept ground impact, and has an effect of slip resistance; 4, the heel made of the TPU materials is tightly fastened with a shoe upper, therefore, the sole is firmly integrated with the shoe upper, so that when a sporter is running, the rear foot is more stable; and 5, the sole is light in weight, is waterproof, and can guarantee the foot feel to be always in the best state.

Description

technical field [0001] The invention relates to a shoe sole structure, in particular to a shock-absorbing and boosting shoe sole. Background technique [0002] Existing soles are of a great variety, such as rubber, PU, ​​EVA, PHYLON, TPP, and those with shock absorption and cushioning functions. [0003] Rubber sole: used for outsoles of various sports shoes. Advantages: good wear resistance, non-slip, elastic, not easy to break, good softness, good extensibility, stable shrinkage, good hardness, good bendability. Disadvantages: heavy weight, easy to spit frost (a quality problem), not easy to corrode (environmental protection problem). [0004] PU: High molecular polyurethane synthetic material, used in the midsole of basketball and tennis shoes, and can also be directly used in the outsole of casual shoes. Advantages: high density, high hardness, wear resistance, good elasticity, good oxidation resistance, easy to corrode, good for environmental protection, not easy to ...

AI Technical Summary

Problems solved by technology

Disadvantages: heavy weight, easy to spit frost (a quality problem), not easy to corrode (environmental protection problem)

Disadvantages: strong water absorption, easy to turn yellow, easy to break, poor elongation, not resistant to water, easy to rot at the bottom

Disadvantages: easy to absorb water, not easy to corrode, not conducive to environmental protection, easy to get dirty

Disadvantages: not easy to corrode, not conducive to environmental protection, easy to wrinkle and shrink at high temperature

Disadvantages: heavy material, poor wear (not wear-resistant), poor softness, poor bendability (not resistant to folding), poor shock absorption

The specific gravity of the rubber sole is also large, but it is soft, very wear-resistant, and has strong grip, but poor elasticity. It is generally used in indoor football shoes and casual shoes.
